The Kingsguard

The Kingsguard, also known as the White Cloaks, are a group of seven annointed knights chosen by the ruler of the Seven Kingdoms to serve as his protectors.

Traditionally chosen from the best knights throughout the realm, the Kingsguard has included many of the most skilled swordsmen in Westerosi history. Sworn to protect the king and his family at all costs, they represent an elite guard that nominally forsake all family loyalties, wives, and fathering children, much like the Night's Watch.

During Robert's Rebellion, five members of the Kingsguard - Ser Arthur Dayne, Prince Lewyn Martell, Ser Jonothor Darry, Ser Gerold Hightower and Ser Oswell Whent - were killed in the defense of the royal family, with only Jaime Lannister and Barristan Selmy surviving. Barristan Selmy was pardoned by Robert Baratheon following the war, and joined his new kingsguard as Lord Commander.

The other six members of Robert Baratheon's Kingsguard were Ser Jaime Lannister, Mandon Moore, Boros Blount, Preston Greenfield, Meryn Trant, and Arys Oakheart.

Following Robert's death and Joffrey Baratheon's coronation, Barristan Selmy was relieved of his position and replaced by Sandor Clegane. This was considered to be a significant departure from tradition, as before, a member of the Kingsguard served for life.

Jaime Lannister was also subsequently promoted to Lord Commander.

Following Sandor Clegane's desertion and Ser Mandon Moore's death during the Battle of Blackwater, Osmund Kettleblack and Balon Swann joined Joffrey's Kingsguard. After Meryn Trant's death in Braavos at the hands of Arya Stark, a reanimated Ser Gregor Clegane joined the Kingsguard as well.

Other rulers around the world have also established their own versions of a Kingsguard. Daenerys Targaryen founded a Queensguard, which includes Ser Jorah Mormont, Kovarro, Aggo, and formerly Rakharo and Ser Barristan Selmy.

Renly Baratheon named his Kingsguard the Rainbow Guard, with each member wearing a different color cloak. They were: Ser Loras Tyrell, Brienne of Tarth, Ser Robar Royce, and Ser Emmon Cuy.
